As the post states, all player built structures, vehicle placement as well as all the charactars created will be wiped on all servers. However, the account-locked items will survive, such as crates, crate keys and cosmetic skins you found in crates or won from Battle Royale.

What if you bought the premium?

For people who purchased the Premium or upgraded to the Premium Edition will be topped off up to 3 Airdrop Tickets. If you already have 3 or more Airdrop Tickets you won’t be receiving any additional ones. This won’t happen at the exact time of the wipe but will be granted to your account within a few business days afterward.
